One of the most interesting announcements to come out of the Apple iPhone 4S event was the new “Cards” app. Like the “Find my Friends” app, there wasn’t much information made available about the new Cards service, but that changed today. Apple says that the app is “Coming Soon”.

As we reported today, postcard apps like Postagram weren’t worried about Apple’s ‘Card’, but it will be interesting to see what Sincerely has to say now that details have been revealed.

Apple discloses the pricing for Cards today:

Each card is just $2.99 when sent within the U.S. and $4.99 when sent to or from anywhere else. And that includes postage.

Using the app, you will be able to take pictures, choose a design that you want, and then enter an address for it to be sent to. No need to buy a stamp Apple says, and you’ll even be notified when your card is delivered using the United States Postal Service Intelligent Mail barcode. That’s pretty high tech.

We’re pretty sure that this is the first time that Apple has let you create your own digital goods and then purchase them afterwards, with the intention of sending them as a gift. Of course, you’ve been able to engrave iPods for a while now, which was always a nice personal touch. This takes personalization to a new level for Apple, though.
